- Maximum aperture with the 1.4x and 2.0x tele-converters is F4 and F5.6, respectively.
- α9 software must be updated to the latest version to activate when this lens is used with the α9. Refer to the Sony support site for camera body compatibility information
- A normal filter is initially installed in the filter slot. The filter is part of the lens’s optical system, and either the normal filter or circular polarizer should always be in place when using the lens. Be sure that a filter is installed before memorizing the focus point for the preset focus function
- Support for this feature is currently only planned for the α9. The maximum continuous shooting speed of an α9 body fitted with the FE 400mm F2.8 GM OSS will be 20 fps at F11 and larger, and 10 fps at F13 and smaller (Latest α9 software, “Hi” continuous shooting mode, focus priority, 1/125 or faster shutter speed). Maximum shooting speed will depend on settings and conditions
